Abstract (en)

[origin: EP2257085A1] The present invention disclose a method for notifying the change of cell information, which comprises: a first base station sends a serving cell change message to a second base station, wherein the serving cell change message carries one or more of the following information: cell adding information, cell deleting information, cell modifying information; in response to the serving cell change message, the second base station updates local information according to the information carried in the serving cell change message. With the present invention, the neighboring cell list may be updated in time, the management of the neighboring cell list performed by the base station is facilitated, and the switching strategy is optimized.
